On March 19, 2026, Medifast, Inc.

Cooperation Agreement

This Cooperation Agreement (this “Agreement”) is made and entered into as of March 19, 2026, by and among Medifast, Inc. (the “Company”), Steamboat Capital Partners, LLC (“Steamboat”) and each of the other related Persons (as defined below) set forth on the signature pages hereto (collectively with Steamboat, the “Steamboat Group”). The Steamboat Group and each of their Affiliates (as defined below) and Associates (as defined below) are collectively referred to as the “Investors”. The Company and the Investors are referred to herein as the “Parties”.

RECITALS

WHEREAS, the Steamboat Group Beneficially Owns (as defined below) shares of common stock, par value $0.001 per share, of the Company (the “Common Stock”) totaling, in the aggregate, 657,590 shares of Common Stock as of 5:00 pm on the date hereof; and

WHEREAS the Company and the Investors have determined to come to an agreement with respect to the nomination of members of the Company’s board of directors (the “Board”) at the 2026 annual meeting of stockholders of the Company (including any adjournment or postponement thereof, the “2026 Annual Meeting”) and certain other matters, as provided in this Agreement.

NOW, THEREFORE, in consideration of the foregoing premises and the mutual covenants and agreements contained herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties hereto, intending to be legally bound hereby, agree as follows:

1.Board Matters. (a) The Company agrees to take all necessary actions to nominate at the 2026 Annual Meeting the following seven (7) persons to serve as directors of the Board with a term expiring at the 2027 annual meeting of stockholders of the Company (including any adjournment or postponement thereof, the “2027 Annual Meeting”): Daniel Chard; Elizabeth Geary; Scott Schlackman; Andrea Thomas; Ming Xian; Parsa Kiai; and Jeffrey Rose (the “Agreed Nominees”). The Company currently intends to hold the 2026 Annual Meeting on May 19, 2026 and agrees to use its reasonable best efforts to hold the 2026 Annual Meeting no later than June 19, 2026. The Company shall recommend that the Company’s stockholders vote in favor of each of the Agreed Nominees at the 2026 Annual Meeting.

(b)Each of the Investors agrees not to nominate any person for election to the Board at the 2026 Annual Meeting or submit any stockholder proposal for consideration at the 2026 Annual Meeting. At the 2026 Annual Meeting, each of the Investors agrees to appear in person or by proxy and to vote all of the Voting Securities (as defined below) it Beneficially Owns (i) in favor of the election of the Agreed Nominees, (ii) to ratify the appointment of RSM US LLP as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2026, (iii) in accordance with the Board’s recommendation with respect to the Company’s “say-on-pay” proposal, (iv) in favor of an amendment to the Company’s Amended and Restated 2012 Share Incentive Plan to increase the number of shares reserved for

issuance thereunder and (v) in accordance with the Board’s recommendation with respect to any stockholder proposals or other business presented at the meeting (other than (x) amendments to the Company’s Certificate of Incorporation or Bylaws that diminish stockholder rights or (y) Extraordinary Transactions ((x) and (y), collectively, the “Permitted Matters”), on which the Investors shall be permitted to vote in their discretion). As used in this Agreement, an “Extraordinary Transaction” shall mean any tender offer or exchange offer, merger, acquisition, business combination, reorganization, restructuring, recapitalization, sale or acquisition of assets, liquidation, or dissolution involving the Company or any of its Affiliates or its or their securities or the assets or businesses of the Company or any of its Affiliates.

(c)Unless the Restricted Period has expired pursuant to Section 2(d), the Company will nominate the Steamboat Designees (as defined below) (and any substitute person appointed pursuant to Section 1(e) hereof) to its slate of nominees for election as directors of the Company at the 2027 Annual Meeting; provided, that the Company shall not be required to nominate any Steamboat Designee (as defined below) if the Steamboat Group ceases at any time to collectively Beneficially Own two percent (2%) or more of the outstanding Voting Securities (as defined below). The Company shall recommend that the Company’s stockholders vote in favor of each of the Steamboat Designees at the 2027 Annual Meeting. At the 2027 Annual Meeting, each of the Investors agrees to appear in person or by proxy and to vote all of the Voting Securities it Beneficially Owns (i) in favor of the election of the nominees recommended by the Board for election, (ii) to ratify the appointment of the independent registered public accounting firm designated by the Board as the Company’s independent registered public accounting firm for such fiscal year, and (iii) in accordance with the Board’s recommendation with respect to any stockholder proposals or other business presented at the meeting (other than with respect to any Permitted Matter, on which the Investors shall be permitted to vote in their discretion).

(d)The Company agrees that each of the Steamboat Designees will be considered along with all other Board members for Board committee appointments in connection with the Board’s annual review of committee composition. The Board will not utilize committees of the Board for the purpose of excluding any of the Steamboat Designees in order to limit his or her participation in substantive deliberations of the Board.

(e)The Company agrees that if any of Parsa Kiai or Jeffrey Rose (collectively, including any substitute person recommended pursuant to this Section 1(e), the “Steamboat Designees”) is unable to serve as a director, resigns as a director or is removed as a director without cause prior to the 2027 Annual Meeting, then the Steamboat Group shall have the ability to recommend a substitute person for appointment or election to the Board; provided, that any substitute person recommended by the Steamboat Group shall qualify as “independent” pursuant to New York Stock Exchange listing standards and have relevant financial and business experience to fill the resulting vacancy. In the event the Nominating/Corporate Governance Committee of the Board (the “NCG Committee”) does not accept a substitute person recommended by the Steamboat Group, the Steamboat Group will have the right to recommend additional substitute persons for consideration by the NCG Committee. Upon the acceptance of a replacement director nominee by the NCG Committee, the Board will take such actions as

-2-

necessary to appoint such replacement director to the Board no later than five (5) business days after the NCG Committee’s recommendation of such replacement director.

(f)As of the date of this Agreement, each of the Parties represents and warrants to the other Parties that it is not aware of any facts that would suggest that any of the Agreed Nominees: (i) is not “independent” in accordance with the listing standards for the New York Stock Exchange and any other applicable director independence standards (other than Daniel Chard, the Company’s Chairman and Chief Executive Officer); (ii) is not otherwise qualified to serve as a director of the Company in accordance with the Company’s Corporate Governance Guidelines and Code of Conduct and Business Ethics, including all applicable conflict of interest, confidentiality, stock ownership and insider trading policies and guidelines of the Company (collectively, the “Governance Guidelines”); or (iii) is a party to (A) any agreement, arrangement or understanding with any Person (I) concerning how such Agreed Nominee, if elected as a director of the Company, will act or vote on any issue or question or (II) that could limit or interfere with such Agreed Nominee’s ability to comply, if elected as a director of the Company, with such Agreed Nominee’s fiduciary duties under applicable law or (B) any agreement, arrangement or understanding with any person other than the Company with respect to any direct or indirect compensation, reimbursement or indemnification in connection with service or action as a director of the Company (such agreements, arrangements or understandings, “Restrictive Agreements”). Each of the Parties acknowledges and agrees that each of the Agreed Nominees (and each substitute person recommended pursuant to Section 1(e) hereof) will be required to: (w) comply with all policies, procedures, processes, codes, rules, standards and guidelines applicable to members of the Board, including the Governance Guidelines; (x) not enter into any Restrictive Agreements; (y) keep confidential all Company Confidential Information (as defined below) and not disclose to any third parties discussions or matters considered in meetings of the Board or Board committees (other than to the limited extent permitted under Section 4 hereof); and (z) complete the Company’s standard director and officer questionnaire and other reasonable and customary director documentation (including a representation and agreement as contemplated by the Bylaws) required by the Company in connection with the election of Board members. Upon election to the Board, each of the Agreed Nominees will be subject to the same protections and obligations, and shall have the same rights and benefits, as are applicable to all other directors of the Company.

2.Standstill. (a) From and after the date of this Agreement until the day that is three (3) months following the date of the 2027 Annual Meeting (such period, the “Restricted Period”), none of the Investors shall, directly or indirectly, and each Investor agrees and shall cause each of its Affiliates and Associates not to, directly or indirectly, with respect to the Company (it being understood that the foregoing shall not restrict any of the Steamboat Designees from discussing such matters addressed below privately with other members of the Board solely in his or her capacity as a director in a manner consistent with his or her fiduciary duties to the Company so long as such discussions would not reasonably be likely to require public disclosure by the Steamboat Group):

(i) solicit proxies or written consents of stockholders (including, without limitation, any solicitation of consents with respect to the call of a special meeting of

-3-

stockholders) or conduct any other type of referendum (binding or non-binding) with respect to, or from the holders of, the voting securities of the Company (“Voting Securities”), or become a “participant” (as such term is defined in Instruction 3 to Item 4 of Schedule 14A promulgated by the Securities and Exchange Commission (the “SEC”) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) in or in anyway engage or assist any third party in any “solicitation” (as such term is defined under the Exchange Act) of any proxy, consent or other authority to vote or withhold from voting any Voting Securities;

(ii) except with respect to the Permitted Matters, encourage, advise or influence any Person, or assist any third party in so encouraging, advising or influencing any Person, with respect to the giving or withholding of any proxy, consent or other authority to vote any Voting Securities or in conducting any type of referendum;

(iii) form, join or in any way participate in a partnership, limited partnership, syndicate or “group” (as defined under Section 13(d) of the Exchange Act), with respect to the Voting Securities (other than a “group” that includes only other members of the Steamboat Group), or otherwise support or participate in any effort by, or enter into any discussions, negotiations, arrangements or understandings with, a third party with respect to the matters set forth in this Section 2;

(iv) seek or encourage any Person to submit nominations in furtherance of a “contested solicitation” for the election or removal of directors with respect to the Company or seek, encourage or take any other action with respect to the election or removal of any directors or with respect to the submission of any stockholder proposal, except that this clause (iv) shall not limit the rights of the Steamboat Group as expressly set forth in Section 1(e) of this Agreement;

(v) present (or request to present) at any annual meeting or any special meeting of the Company’s stockholders or in connection with any action by written consent, any proposal for consideration for action by stockholders or propose (or request to propose) any nominee for election to the Board or seek representation on the Board or the removal of any member of the Board, except that this clause (v) shall not limit the rights of the Steamboat Group as expressly set forth in Section 1(e) of this Agreement;

(vi) except with respect to the Permitted Matters, grant any proxy, consent or other authority to vote with respect to any matters (other than to the named proxies included in the Company’s proxy card for any annual meeting or special meeting of stockholders) or deposit any Voting Securities in a voting trust or subject them to a voting agreement or other arrangement of similar effect (excluding customary brokerage accounts, margin accounts, prime brokerage accounts and the like);

(vii) make any request under Section 220 of the Delaware General Corporation Law (other than under Section 220(d) solely in a Steamboat Designee’s capacity as a director in a manner consistent with his or her fiduciary duties to the Company) or other

(viii) institute, solicit, assist or join as a party, any litigation, arbitration or other proceeding against or involving the Company or any of its current or former directors or officers (including derivative actions), other than to enforce the provisions of this Agreement or in connection with shares owned by members of the Steamboat Group being treated differently than other shares or in connection with claims for indemnification by any Steamboat Designee;

(ix) engage in any short sale or any purchase, sale or grant of any option, warrant, convertible security, stock appreciation right, or other similar right (including, without limitation, any put or call option or “swap” transaction) with respect to any security (other than any index fund, exchange traded fund, benchmark fund or broad basket of securities) that includes, relates to or derives any significant part of its value from a decline in the market price or value of the Company’s securities; or take any action which would cause or require the Company to make public disclosure regarding any of the foregoing or request, directly or indirectly, any amendment or waiver of the foregoing in a manner that would reasonably be likely to require public disclosure by the Investor or the Company.

(b)As used in this Agreement: (i) the term “Beneficial Owner” shall have the same meaning as set forth in Rule 13d-3 promulgated by the SEC under the Exchange Act, except that a Person will also be deemed to beneficially own (A) all Voting Securities which such Person has the right to acquire pursuant to the exercise of any rights in connection with any securities or any agreement, regardless of when such rights may be exercised and whether they are conditional, and (B) all Voting Securities in which such Person has any economic interest, including, without limitation, pursuant to a cash settled call option or other derivative security, contract or instrument in any way related to the price of any Voting Securities (and the term “Beneficially Own” shall have a correlative meaning); and (ii) the terms “Person” or “Persons” shall mean any individual, corporation (including not-for-profit), general or limited partnership, limited liability company, joint venture, estate, trust, association, organization or other entity of any kind or nature.

-5-

(d)Without limiting any of the Parties’ rights or remedies under this Agreement, in the event that the Company does not nominate or appoint one of the Steamboat Designees as a director in accordance with the terms of this Agreement, then the Restricted Period shall be deemed to expire on the day that is thirty (30) days prior to the expiration of the Company’s advance notice period for the nomination of directors at the 2027 Annual Meeting.

3.Non-Disparagement. During the Restricted Period, the Company, on the one hand, and each Investor, on the other hand, will each refrain from making, and will cause their respective Affiliates and Associates and its and their respective Representatives (as defined below) not to make, any statement or announcement that relates to or constitutes an ad hominem attack on, or that relates to and otherwise disparages, impugns or is reasonably likely to damage the reputation of, (a) in the case of statements or announcements by or on behalf of such Investor, the Company or any of its Affiliates or Associates or any of its or their respective officers, directors or employees or any person who has served as an officer, director or employee of the Company or any of its Affiliates or Associates; and (b) in the case of statements or announcements by or on behalf of the Company, each Investor and its respective Affiliates and Associates and its and their respective principals, directors, officers, employees, members or general partners or any person who has served as such. The foregoing will not prevent the making of any factual statement in any compelled testimony or the production of information, whether by legal process, subpoena or as part of a response to a request for information from any governmental authority with jurisdiction over the Party from whom information is sought nor any statements to members of the Board or Persons attending a meeting of the Board or any committee thereof. For purposes of this Agreement, “Representatives”, with respect to each Party, shall mean such Party’s principals, directors, officers, employees, general partners, members, agents, representatives, attorneys and advisors acting at the direction or on behalf of such Party.

4.Confidentiality The Company understands and agrees that, subject to the terms of, and in accordance with, this Agreement, each of the Steamboat Designees may, if and to the extent he or she desires to do so (and subject to his or her fiduciary duties), confidentially disclose information he or she obtains while serving as a member of the Board or of any committee of the Board to the Steamboat Group. Each member of the Steamboat Group acknowledges and agrees that this information is confidential and proprietary to the Company and may include trade secrets or other business information the disclosure of which could harm the Company. In consideration for, and as a condition of, the information being furnished to the Steamboat Group and, subject to the restrictions set forth in this Section 4, each member of the Steamboat Group agrees to treat any and all information concerning or relating to the Company or any of its Affiliates or Associates that is furnished to it or to any of the Steamboat Designees (regardless of the manner in which it is furnished, including in written or electronic format or orally, gathered by visual inspection or otherwise) by any of the Steamboat Designees, or by or on behalf of the Company or any of its Representatives, together with any notes, analyses, reports, models, compilations, studies, interpretations, documents, records or extracts thereof containing, referring, relating to, based upon or derived from such information, in whole or in part (collectively, “Company Confidential Information”), in accordance with the provisions of this Agreement. Each member of the Steamboat Group will, and will cause its Representatives

-6-

to, (a) keep the Company Confidential Information strictly confidential and (b) not disclose any of the Company Confidential Information in any manner whatsoever without the prior written consent of the Company; provided, however, that members of the Steamboat Group may privately disclose any of such information to their respective Representatives (i) who need to know such information for the sole purpose of advising such member of the Steamboat Group on its investment in the Company and (ii) who are informed by such member of the Steamboat Group of the confidential nature of such information and agree to abide for the benefit of the Company to the terms hereof; provided, further, that such member of the Steamboat Group will be responsible for any violation of this Agreement by its Representatives as if they were parties hereto. It is understood and agreed that none of the Steamboat Designees shall disclose to the Steamboat Group or its Representatives any Legal Advice (as defined below) that may be included in the Company Confidential Information with respect to which such disclosure may constitute waiver of the Company’s attorney-client privilege or attorney work-product privilege. “Legal Advice” as used herein shall include any advice provided by legal counsel that is protected by the attorney-client or attorney work-product privilege. The obligations set forth in this Section 4 shall expire one (1) year after the date on which the last of the Steamboat Designees (or any other representative of the Steamboat Group) no longer serves as a director of the Company; provided, that each member of the Steamboat Group shall maintain in accordance with the confidentiality obligations set forth herein any Company Confidential Information constituting trade secrets for such longer time as such information constitutes a trade secret of the Company.

5.Representations and Warranties of the Company. The Company represents and warrants to the Steamboat Group that: (a) the Company has the corporate power and authority to execute this Agreement and to bind it thereto; (b) this Agreement has been duly and validly authorized, executed and delivered by the Company, constitutes a valid and binding obligation and agreement of the Company and is enforceable against the Company in accordance with its terms, except as enforcement thereof may be limited by applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance or similar laws generally affecting the rights of creditors and subject to general equity principles; and (c) the execution, delivery and performance of this Agreement by the Company does not and will not (i) violate or conflict with any law, rule, regulation, order, judgment or decree applicable to the Company, (ii) result in any breach or violation of or constitute a default (or an event which with notice or lapse of time or both could constitute such a breach, violation or default) under or pursuant to, or result in the loss of a material benefit under, or give any right of termination, amendment, acceleration or cancellation of, any organizational document, agreement, contract, commitment, understanding or arrangement to which the Company is a party or by which it is bound or (iii) result in or constitute a change in control for purposes of any of the Company’s existing severance, compensation or change in control agreements and arrangements.

7.Press Release. Following the execution of this Agreement, the Company and the Investors shall jointly issue a mutually agreeable press release announcing certain terms of this Agreement.

8.Specific Performance. Each Investor, on the one hand, and the Company, on the other hand, acknowledges and agrees that irreparable injury to the other Parties hereto would occur in the event any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached and that such injury would not be adequately compensable by the remedies available at law (including the payment of money damages). It is accordingly agreed that each Investor, on the one hand, and the Company, on the other hand (the “Moving Party”), shall be entitled to specific enforcement of, and injunctive relief to prevent any violation of, the terms hereof, and the other Parties hereto will not take action, directly or indirectly, in opposition to the Moving Party seeking such relief on the grounds that any other remedy or relief is available at law or in equity. This Section 8 is not the exclusive remedy for any violation of this Agreement.

9.Expenses. Each Party shall each be responsible for its own fees and expenses incurred in connection with the negotiation, execution and effectuation of this Agreement and the transactions contemplated hereby, including, but not limited to, any matters related to the 2026 Annual Meeting.

10.Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions of this Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated. It is hereby stipulated and declared to be the intention of the Parties that the Parties would have executed the remaining terms, provisions, covenants and restrictions without including any of such which may

-8-

be hereafter declared invalid, void or unenforceable. In addition, the Parties agree to use their best efforts to agree upon and substitute a valid and enforceable term, provision, covenant or restriction for any of such that is held invalid, void or unenforceable by a court of competent jurisdiction.

Medifast Announces Cooperation Agreement with Steamboat Capital

Company Agrees to Nominate Parsa Kiai and Jeff Rose as Director Candidates at 2026 Annual Meeting of Stockholders

BALTIMORE, March 20, 2026 -- Medifast, Inc. (NYSE: MED) the metabolic health and wellness company known for its science-backed, coach-guided lifestyle system, today announced the company's Board of Directors has agreed to nominate Parsa Kiai and Jeff Rose from Steamboat Capital Partners LLC as independent director candidates to stand for election at the company’s 2026 Annual Meeting of Stockholders, which is provisionally scheduled for May 19, 2026. These nominations are pursuant to a Cooperation Agreement entered into between the company and Steamboat Capital, which beneficially owns above 5% of the company’s outstanding shares.

The Board of Directors has determined that Medifast’s directors Jeffrey Brown and Michael Hoer will not stand for reelection. Medifast Chairman & Chief Executive Officer Dan Chard will continue in his current role, and as previously announced, will step down as CEO on June 1, 2026, while remaining Chairman. Nicholas Johnson, President of Medifast, is expected to succeed Dan Chard as CEO following his departure.

"We are pleased to nominate these talented independent leaders for election to our Board of Directors at the upcoming Annual Meeting. Their experience and perspectives would complement the work already underway to support Medifast’s development and strategic priorities as a metabolic health company," said Mr. Chard. "Our team remains focused on returning the company to profitability, growing our business and independent coach network, and maintaining a rigorous commitment to scientific innovation in this space. We have been executing with discipline against this strategy, and we look forward to a productive collaboration with Steamboat Capital as we continue our efforts to build on that progress and accelerate improvements in financial performance to maximize returns for our stockholders."

Mr. Chard continued, “On behalf of the entire Board, we also want to thank Jeffrey Brown and Michael Hoer for their service on the Board and for their many contributions to Medifast.”

"We are pleased to have reached this agreement through a constructive and collaborative dialogue with the Medifast Board and management team," said Parsa Kiai Managing Partner

and Chief Investment Officer at Steamboat Capital. "We have a strong appreciation for the progress the company is making and believe the market is significantly undervaluing the company’s substantial financial and intrinsic assets as well as its long-term potential. We welcome the opportunity to work with the Board to support Medifast’s continued evolution as a business. Medifast’s independent coach network and comprehensive metabolic health system represent a differentiated and compelling platform, and we’re looking forward to working together in a spirit of collaboration to build on this foundation, drive sustainable profitability, and unlock long-term value for stockholders."

Pursuant to the Cooperation Agreement, Steamboat Capital and certain of its affiliates have agreed to certain customary standstill and voting provisions through the company's 2027 Annual Meeting of Stockholders. The agreement will be filed on a Form 8-K with the Securities and Exchange Commission.
